Triscilidee a sect of Sabellian heretics mentioned by Philaster (Hcer. c. xciii), Augustine (Hrer. 100. 74), and Predestinatus (Haer. 100. 74) as maintaining the opinion that the divine nature is composed of three parts, one of which is named the Father, the second part the Son, and the third the Holy Ghost; and that the union of these three parts constitutes the Trinity. Philaster, in condemning this heresy, uses expressions very similar to some in the Athalnasian hymn, "Ergo est vera persona Patris quae misit Filium, et est vera persona quae advenit de Patrae est vera persona Spiritus quae a Filio et Patre missa est."
